BMW Drivetrain Parts for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

This Genuine BMW Motorsport part (used on the Sport Evo M3s) is a precision machined and balanced lightweight steel flywheel. The stock flywheel weights 19.5 lbs, the Motorsport flywheel is under 12 lbs! This lightweight flywheel will allow the motor to "spool up" faster, improving acceleration. This is a perfect flywheel upgrade for someone who does not want a full aluminum lightweight flywheel and also wants factory Motorsport parts on the E30 M3. After the Turner performance chip this is the next biggest "bang for the buck" for your M3. Flywheel mounting bolts available separately.

This item fits the following BMWs:
1987-1991 E30 BMW M3
